PATH: ACTUAL VALUES ÖØ A2 METERING DATA ÖØ VOLTAGE METERING
Measured voltage parameters will be displayed here. The V/Hz measurement is a per unit value based on Vab voltage/
measured frequency divided by VT nominal/nominal system frequency. Polar coordinates for measured phase and/or line
voltages are also shown using Va (wye connection) or Vab (open delta connection) as a zero angle reference vector. In the
absence of a voltage signal (Va or Vab), IA output current is used as the zero angle reference vector.
If
VT CONNECTION TYPE is programmed as "None" and NEUTRAL VOLTAGE TRANSFORMER is "No" in S2 SYSTEM, the follow-
ing flash message will appear when an attempt is made to enter this group of messages.
